【Abstract】 The theoretical foundation of the single step Houbolt algorithm is expounded. A finite element model of the assembly of the breech mechanism of a self propelled Howitzer is established.Based on elastoplastic theory and multi body contact algorithm,static and dynamic finite element analysis of the structural system is performed.The simulation results indicate that the strength of each component in the structural system is satisfactory.更多还原
